Sigenergy Battery Systems in Townsville

Barra Solar Power installs Sigenergy batteries in Townsville and across North Queensland. We design and fit Sigenergy home battery systems for local homes, starting with how your household actually uses power: your existing solar, your switchboard, single or three phase supply, and what you want the battery to do. Then we design a system to suit.

Sigenergy’s SigenStor is a modular system. The energy controller, battery modules and optional EV charging stack together into one unit, so a system can start at a size that makes sense now and grow later. Our local team handles the design, the installation and the paperwork, and we’re here for support after the job is done. Our team of Sigenergy-trained electricians designs, installs and supports every system.

SigenStor Energy Controller

The Sigen Energy Controller (SigenStor EC) is the core of a SigenStor system. It manages solar, battery and household loads together.

5.0–12.0 kW single phase models and 5.0–30.0 kW three phase models
Built-in energy management system (EMS) for precise control
Up to 2.0 DC/AC ratio on single phase models, so more solar panels can be connected relative to inverter size
Unbalanced three-phase output on three phase models
150% peak output power in off-grid mode (for 10 seconds, per Sigenergy’s datasheet) for appliances with a high start-up draw
Up to 4 MPP trackers, useful for roofs with panels facing different directions
Connects 1 to 6 SigenStor BAT modules (5.0 or 8.0 models) per controller
IP66 rated, with an operating range of −30 °C to 60 °C

Sigen Battery (SigenStor BAT)

Lithium iron phosphate (LFP) cells, 280 Ah
Rated to 10,000 cycles*
100% depth of discharge, so the full usable capacity can be used
Pack-level battery optimisation: modules can be mixed and matched, and the system upgraded later
Higher energy density for a compact footprint
Five layers of battery safety protection (below)

*Cycle figure provided by the battery cell manufacturer, based on cell test conditions of 25 ± 2 °C, 0.5C charge and discharge rate and SOH = 60%.

Battery safety: five layers of protection

Sigenergy builds several layers of protection into each battery module:

Cell-level temperature monitoring
Internal fire extinguishing kit
High-temperature-resistant insulated pads
Aerogel insulated pads
Decompression valve

Battery status can be checked in real time in the mySigen App.

Backup power and switching

With the right equipment, a SigenStor system can switch between energy sources (grid, solar, battery, generator and a compatible EV) without interrupting the home. Sigenergy specifies a 0 ms load-side disruption time for its backup switch. That figure applies when a Sigen Energy Gateway is installed with the Sigen Energy Controller and Sigen Battery, and when the controller’s nominal power is higher than the total load in the home at the time.

What stays on in a blackout depends on how the system is configured: which circuits are backed up, the size of the battery and inverter, and the state of charge when the grid goes down. We’ll talk this through with you during design.

Sigen Hybrid Inverter

For homes that suit a wall-mounted inverter, the Sigen Hybrid Inverter connects to Sigen Battery modules through the SigenStor BC battery controller.

99 mm ultra-slim design
25 dB operating noise
IP66 rated, with an operating range of −30 °C to 60 °C
Up to 99.0% maximum efficiency
200% peak output power while off-grid (three phase models, 10 seconds)
200% DC/AC ratio for higher solar yield

EV charging: SigenStor EVDC

The Sigen EV DC Charging Module is part of the SigenStor stack, so the battery system and a DC EV charger share one unit.

25 kW bi-directional DC charging
150–1000 V charging voltage range
IP66 rated
Can charge your EV from your own solar
V2X-integrated: Sigenergy describes it as the world’s first V2X-integrated all-in-one home energy system. V2X depends on the vehicle’s own capabilities, so we’ll check your EV before you rely on it.

An AC option, the Sigen EVAC Charger, is also available.

The mySigen App

Real-time monitoring of energy flow on the home screen
Sigen AI Mode: smart scheduling that adapts to weather, tariffs and your usage pattern
Energy Sankey diagram: see where each watt comes from and where it goes
Sigen AI Assistant: built-in system diagnostics
Strategy Insight: AI analysis of the system’s operating strategy
Battery Energy Source: real-time view of where the battery’s stored energy came from

¹ Load-side disruption time. Requires a Sigen Energy Gateway used together with the Sigen Energy Controller and Sigen Battery. Test conditions: grid in open-circuit state, with the controller’s nominal power higher than the total power of the home loads.
² Optional feature, only supported on certain models.
³ Sigenergy publishes the full certificate list on its website.

Warranty

Sigenergy’s product warranty terms for your chosen controller, battery modules and accessories are set out in your quote. Our installation work is backed by Barra Solar Power’s 10-year workmanship guarantee.

Is Sigenergy right for your home?

Sigenergy is often a good fit if you:

want a battery system you can expand later by adding modules
have, or plan to add, a reasonable amount of solar and want to use more of it at night
are thinking about an EV now or down the track, and like the idea of DC charging built into the same system
want clear monitoring and control from an app
have single or three phase power (there are controller models for both)

It may not be the best choice for every home. Space, switchboard condition, existing inverters, your supply type and your budget all come into it. If another brand suits you better, we’ll say so. We also install Tesla Powerwall 3, Sungrow and SolaX, and BYD on some existing systems. See all our battery systems.

Frequently asked questions

Sigenergy FAQs

01Can I add more battery capacity later?

Yes, within limits. Each Sigen Energy Controller supports 1 to 6 SigenStor BAT modules (5.0, 8.0 or 10.0 models). If you expect your usage to grow, for example with an EV or a pool, we can plan for that in the initial design.

02Will a Sigenergy battery keep my power on in a blackout?

It can, for a Townsville blackout, when the system is set up for backup. Seamless switching needs a Sigen Energy Gateway. We do not promise whole-home backup by default — what stays on depends on which circuits are backed up, inverter size and battery charge. We'll explain what's realistic for your home before you decide. More on will a home battery work during a Townsville blackout.

03Do I need single phase or three phase?

That's set by your home's electricity supply. Sigenergy makes single phase controllers from 5.0 to 12.0 kW and three phase controllers from 5.0 to 30.0 kW. We check your supply and switchboard as part of the site assessment.

04Will it work on the Ergon Energy network?

Yes. Ergon must approve it before we connect it, even if it won't export. On a single-phase home, the SigenStor's inverter counts toward Ergon's 10 kVA limit, and export is usually capped at 5 kW per phase on a basic connection. Read more about solar and batteries on Ergon in Townsville.
